Specification of Letters Patent.

Patented April 2, 1907.

Application filed November 2, 1905. Serial No. 285,525.

have invented a certain new and useful Improvement in Center-Stop Trolley-Brackets, of which the following is a specification, reference being had to the drawings accompanying and formin a part of the same.

This invention re ates to wall center-stop brackets, being particularly adapted to be used with door-hangers.

In the illustrative form of this invention shown in the drawings, in which the same nu meral refers to similar parts, Figure 1 shows a side elevation of a building, with the sto bracket shown in operative relation to tie trolley-track and the doors. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is a front elevation of the preferred form of stop-bracket. Fig. 4 is a front elevation of a modified form of stop-bracket, and Fig. 5 is a side elevation of the bracket shown in Fig. 4.

In the illustrative form of this invention shown in the drawings the trolley-track 3 is supported, by means of the supports 2, on

is attached to a building, such as a barn. Within the track 3, which, as shown, is a hollow one, are located the trolleys 8, having pendants 9 and plates 6, which are secured to the doors 4 and 5 by means of suitable screws, such as 7. The stop-bracket 17 is mounted midway of the length of the track and has a vertical car 19, through which is passed a bolt 13 in the opening 10, securing the bracket to the heading or face-plate.

11 is a lug formed integral with the bracket and adapted to snugly fit in an opening within the face-plate. In this form of the stop-bracket the bracket is securely held to the building by means of this lug 11 and the bolt 13,previously referred to. Depending from the stop-bracket there is a flan e 12, which comes in operative contact with the doors 4 and 5, respectively, to limit the movement of the doors toward each other.

In the form of device 14 shown in Figs. 4 and 5 instead of a single vertical ear, such as 19, of the preferred construction there are two horizontal ears 21 21, having suitable openings through them, as 15 15, for the passage of bolts or screws. (Not shown.) In this construction the bracket-instead of being fitted to the side of the heading or faceplate 1 is secured to the under side of such heading by means of bolts (not shown) passing up through the openings 15 15. In this form the depending flange 16 performs the same function as the flange 12 in the preferred construction.

The stop-bracket 17 is mounted, as shown in Fig. 1, to support the trolley-track and also to secure proper alinement of the doors in a closed position. The depending flange 12 engages the doors to aline them out of the path of the trolleys. By this form of construction the trolleys are never injured by coming into contact with any fixed surface or stop for alining the doors in their closed position. By the use of this invention the trolleys are therefore protected from any sudden jolt or jarring, which they would re ceive if they thus came into direct contact with 'a fixed stop. To insure a close contact of the doors, their upper corners may be cut away, as 18 18, so as to exactly fit the lug 12 of the stop-bracket. By the use of this bracket the movement of the doors is limited, the marring of the face of the doors prevented, and the life of the trolleys prolonged.

Having described several illustrative forms of this device, to the details of which Ido not desire to be limited, what is claimed as new, and what is desired to be secured by Letters Patent, is set forth in the appended claims:

1. In a door-hanger, the combination with the doors, trolleys and track, of a centerstop bracket to support the track and constructed to be engaged by the faces of the doors so as to limit their movement, the said bracket having a depending stop-flange out of the path of said trolley and a vertical ear and a rearwardly-extending lug for firmly attaching it to its support, substantially as described.

2. In a door-hanger, the combination with the doors, trolleys and track, of a centerstop bracket constructed to be engaged by the faces of the doors so as to limit their movement, the said bracket having a depending flange and extensions by means of which it is secured to its support.

3. In a door-hanger, the combination with the doors, trolleys and track of a center-stop bracket constructed to be engaged by the faces of the doors so as to limit their movement, the said bracket having a depending flange and means for firmly supporting it.

4. A stopbracket, having a hollow body portion adapted to support a hollow track, a flange out of the line of said track to engage a door carried by the track, and means to support the bracket.

5. A center-stop bracket, comprising in its construction a hollow body portion, a depending flange, a vertical ear, and a rearwardly-extending lug, substantially as shown and described.

6. A center-stop bracket comprising in its construction a hollow body portion, a depending flange and a vertical ear, substan tially as shown and described.

7. A center-stop bracket, having a depending stop-flange to engage With the face of the doors and with an extension for securing it in its operative position upon the support.

8. In a door-hanger, the combination With the trolleys and track of a center-stop bracket comprising in its construction a hollOW body portion adapted to support the track, means for fastening it to a support and means carried by the stop-bracket to contact With and limit the movement of the door.

9. A stop-bracket provided with an aperture extending therethrough, the walls whereof are adapted to support a hollow track, the lower Wall being substantially in alinement with the Wheel-engaging portion of said track, means to su port the bracket, and means carried by the bracket to engage and limit the travel of a member supported by the hollow track.
